GANG SLlTTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 745,967, dated December1, 1903.

Application filed November 24,1902. Serial No. 132,571. (No model.)

To all whom it may concern:

Be it known thatl, GEORGE MAGNIEN, a citizen of the Republic ofFrance,residing at Kansas City, in the county of Jackson and State ofMissouri, have invented certain new and useful Improvements in GangSlitting-llachines, of which the following is a specification.

My invention relates to gang slitting-machines; and my obj ectis toproduce amachine of this character which will accurately, rapidly, andeasily cut sheet-stock in strips of any desired width within itscapacity for the bodies of cans to contain fruit, milk, meat,vegetables, baking-powder, and a great variety of other goods.

A further object is to produce a machine of this character of simple,compact, strong, rigid, durable, and comparatively cheap construction.

To these ends the invention consists in certain novel and peculiarfeatures of construction and combinations of parts, as hereinafterdescribed and claimed, and in order that it maybe fully understoodreference is to be had to the accompanying drawings, in which- Figure 1is a perspective view of the upper portion of a machine embodying myinvention. Fig. 2 is a vertical cross-section of the same. Fig. 3 is anenlarged detail showing the relative positions of the upper and lowercutting-wheels, one of them being shown partly in section. Fig. l is afront view of a part of the table and feed-bar.

Referring to the drawings in detail, 1 designates the base-plate, whichmay form the top of the bench, of which 2 designates the legs, or itmay, independent of said legs, form a connecting-plate for the verticalstandards 3, bolted to it at 4:. These standards 3 are of the usualbifurcated type to receive the stationary boxes 5 of the lower shaft (5,provided with a longitudinal groove 7, said boxes being by preferencemade of hard bronze and accurately fitted, while the shaft is of forgedsteel, heavy and strong, so as to do away'with any possibility ofspringing, the slightest variation in the shaft endangering thecuttingwheels hereinafter described.

8 designates a pair of similar boxes in the upper portion of thebifurcated brackets and adapted to slide up or down therein, accordingto the direction in which set-screws 9 are turned, said set-screws beingswiveled in the customary manner to the boxes and mounted in the endportions of a bar 10, secured at its ends to the upper ends of saidstandards, locknuts 11 being used to guard against accidental movementof the set-screws.

2 designates the upper shaft, the same being parallel with shaft 6 andjournaled at its ends in adjustable boxes 8. It is also provided with agroove 13.

Mounted on each shaft are cutting-wheels constructed as follows: 14designates a hub having a central cavity 15 in its periphery wherebyaccess may be had with a suitable wrench to the head of the set-screw16, mounted in the hub and projecting into and bearing upon the base ofthe registering groove of the shaft and thereby securing the hub at thedesired point of adjustment. At opposite sides of said cavity the hub isprovided with annular grooves 17, wherein are tightly secured in anysuitable manner rubber rings 18, the latter projecting beyond theperiphery a distance about equal to the projection of the beveledcutting edge of the circular cutter 19, the said cutter being formedwith an annular groove to receive a corresponding flange 21 of the hub.The cutter is clamped rigidly to the hub by means of screw-bolts 22, sothat in case of injury to the cutting edge it will not be necessary toreplace the hub as well as the cutter.

Secured to standards 8 and projecting forwardly therefrom are brackets23, carrying horizontally a feed-table 24:, having parallel grooves 25extending at right angles to the shafts and parallel grooves 26intersecting and extending at right angles to the first-named grooves.An angular gage-plate 27 extends parallel to the first-named grooves forthe purpose of insuring that the stock fed to the cutting-wheels shallfollow the desired course. The said gage is adjustable to accommodatestock of different dimensions through the medium of bolts 28, extendingvertically through the gage and having headed ends engaging grooves 26and their threaded upper ends engaged by clamping-nuts 29. An angularfeed-bar 30 upon the feed-table and extending parallel to the shafts isprovided with bolts 31, having headed or enlarged ends 32 in grooves 25to guide said bar in its movements and to hold it down to its work offeeding the stock to-the rollers. As the peculiarity of construction andrelation existing between feed-table gage 27 and feed-bar 30 is commonin other machinery it is deemed unnecessary to describe it further.

33 designates a bracket secured to front side of each standard 3 at theupper side of feed-table, and each of said brackets carries set-screw 34for raisin or lowering its box 35, wherein is j ournaled the idler-roll36,said roll being adjusted to barely permit the stock to pass beneathit in order that said stock may be held perfectly fiat as it passesbetween the cutting-wheels, and in order to keep the stock straight asit emerges from the machine after being cut I provide a transverse roll37, mounted in bearing 38, bolted to the rear sides of the standards.

The shafts are moved in unison through the medium of the intermeshingguards 39 and 40 on the lower and upper shafts, respectively, andmovement may be imparted thereto through the medium of the crank 41 onshaft 6 by preference or the fast pulley 42 upon such shaft,the latterbeing also equipped with a loose pulley 43, so by shifting the belt (notshown) from one to the other the machine may be started or stopped, asdesired. To conveniently shift the belt, a belt-shifter is provided, thesame consisting of a rod. 4%, mounted slidingly in an opening $5 in thecontiguous bracket .13 a pair of arms t6, adj ustably secured on thesaid rod, and a handle 47, also projecting from the rod.

In the practical operation of the machine the sheet of tin or analogousmaterial is placed upon the table against gage 27 and is fed to themoving cutting-wheels through the medium of the feed-bar 30. The roll 36insures the passage of the stock to the wheels in straight condition, sothat the resilient rings 18 ot' the upper and lower wheels shall synchronously engage the stock and guide and carry it without slippage inposition to be acted upon by the cutting edges of the wheels, the stockemerging from the opposite side of the machine in strips having theirlongitudinal edges perfectly parallel and cleanly cut, and in order tokeep the strips straight the roll 37 supports them until they can beconveniently grasped by an attendant.

It is obvious that the resilient rings by en gagement-with the stock inlines at opposite sides of the center of the hubs more reliably guideand carry such stock thanif a single ring were used, and it will also beapparent that their resiliency or yielding character automaticallyaccommodates stock of varying thicknessthat is to say, the lap of thecutting edges of the wheels determines the thickness, but not thethickness of the stock which can be reliably out by this machineand toadjust the wheels for stock of greater thickness the set-screws 9 aremanipulated in an obvious manner.

From the above description it will be apparent that I have produced amachine embodying the features of advantage enumerated as desirable inthe statement of invention, and while I have illustrated the pre ferredembodiment of such machine it will be apparent that various changes maybe resorted to without departing from its spirit and scope orsacrificing any of its advantages.

Having thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a slitting-machine, a cutting-wheel comprising a hub having aplurality of resilient guide and feed rings upon its periphery, and acutting-plate of greater diameter than the hub rigidly bolted to oneface of said hub.

2. In a slitting-machine, a pair of cooperating cutting-wheelsconsisting of a hub having a plurality of resilient guide and feed ringsprojecting beyond its periphery, and a cutting-plate rigidly bolted toone face of said hub and projecting an equal distance beyond itsperiphery.

In a gang slitting-machine, a pair of shafts, cooperating cuttingwheelsthereon provided with peripherally-projecting rings of resilientmaterial, a feed-table, a single idlerroll on the feed side of thecuttingwheels, and a single driven roll to receive and support the stockas it emerges from said wheels.

In testimony whereof I aflix my signature in the presence of twowitnesses.

GEORGE MAGNIEN.
